Popularity of Openings by Rating

I love how I can search and see which openings I do better with, whether I do better when I trade queens etc. with chess analytics

I would suggest a feature where you can look up the popularity of an opening by rating range. This would be interesting to me, and the data seems to be available.

I imagine this would be better in the suggestions forum; but this might be of interest also (relative).

This is already available. Just open the settings for the Opening Book. You can pick Lichess data and select the rating ranges you want.
